PROCESS OF SAPONIFICAFION.

To all whom, it may concern:

Be it known that I, MARCUS REGINALD ANTHONY SAMUEL, gentleman, a subjectof -the King of Great Britain, residing at 12 vby a process ofsaponifcation, one of the advantages of which is that the process can becarried out in an open pot and that the mineral oil will not separateafter prolonged boiling even when the soap contains very largepercentages of it.

This invention may be carried out in the apparatus shown in Figures 1and 2 inwhich a is a storage tank, b a gage provided with a glassfront,c the outer tube of an injector, (t a tube for conveying steam or otherfluid, c' thc inner injector tube, f an inner pulverizing Vchamberfilled with Wov'en wire netting or cloth, g an outer pulverizing chamber'filled with closely woven Wireicloth, h is the copper or pot.

'Iheffollowing are examplesv illustrating the invention 1 i Exam le I. Amixture of twenty parts tallow, ve parts rosin, five parts petroleumrendered liquid by heat, is placed in the storage tank a. `The mixtureis then led through the pulverizing chambers f and g in a finely dividedstate into the bottomhof thev pot 7i containing a hot caustic sodasolution of a specific gravity of 1.116. After boiling for a very shorttime the operation is coni plete and the curd soap rises to the surface.

If this is allowed to stand for asufiicient time, as in `the ordinaryprocess, it Will throw out all its excess of alkali together with theglycerin and become a closed soap, which may be drawn otll and framed inthe usual way. rlhe proportion of petroleum may be Specification ofLetters Patent.

injected above described, into a weak Patented Dec. 10, 1907.

either largely increased, according to the particular kind of soap ordetergent etc. required. The strength of the alkaline solution may alsobe varied within wide limits, but it is advisable to start with asolution of the strength abovementioned; during the operation thestrength may be increased to about 1.383 specific gravity and reducedwhen necessary at the finish to such strength that the soap can throwout the excess. W'hen it is desired to obtain the usual percentage ofglycerin the strength of the solution should not exceed 1.2 specificgravity. Fixed quantities of alkaline solution and fats etc. may betaken in the correct proportions to form a hydrated soap, or tofacilitate the usual process of soap making fats etc. are

alkaline solution until all the alkali is neu. tralized, and thcnsaltedout in the usual way.

Example ll. A soft soap containing petroleum is madc in exactly the samemanner as hard soap, substituting caustic potash for caustic soda.

that l claim is:-

1. ln aprocess of saponilication injecting a saponiliablc substancesiinultancously with a mineral oil into a solution of caustic alkali.

2. ln'a process of saponilication introducing a saponitiable substancesimultanemisly with a mineral oil in one or more streanis, each streambeing ol` small volume., below the. surface oll a solution of austicalkali.

lin a process of saponi'fication injecting a saponiliable substanc(`simultaneousl)Y with a mineral oil in a finely divided state into asolution of caustic alkali.

4. ln a process of saponilication mixing a saponifiable substance with amineral oil and then injecting the mixture into a solution of causticalkali.
